Metabolife gets a lot of radio and tv commercial time and has many testimonials during their ads. They have received negative publicity on Quackwatch website and according the US Food and Drug Administration the founder, Michael Ellis, was charged with fraud and indicted by a jury.

The critics say that citrus aurantium whcih is in the metabolife ultra product does not help increase metabolism. It is related to ephedra in chemical composition.

Green tea extract which is an ingredient in the formula does seem to increase metabolism but only by a few percent. Research this product as some that receive a lot of radio publicity use advanced marketing techniques and may not be relying on the quality of the product itself.
